In the old testament the temple is a physical location in jerusalem, and springs would flow from under the temple and YHWH would reside in the temple, and trees on both sides for healing, the water when hitting the dead sea would bring life back to it.
Jesus said a spring would bubble within oneself giving life. Between him and some of Pauls letters that YOU are the temple, and it is possible for both the father and son to reside in you, which was the reason for not defiling oneself.
Then by revelation the temple is spiritual in heavens, w/ waters of life and trees of life.
So we have earthly physical, within onesself, and heavenly spiritual.
